이들은 실제로 프로세스 상태입니다. ps가 나타내는 프로세스 상태는 다음과 같습니다.

D Uninterruptible sleep (usually IO)
R Running or runnable (on run queue)
S Interruptible sleep (waiting for an event to complete)
T Stopped, either by a job control signal or because it is being traced.
W paging (not valid since the 2.6.xx kernel)
X dead (should never be seen)
Z Defunct ("zombie") process, terminated but not reaped by its parent.

추가 문자는 다음과 같습니다.

< high-priority (not Nice to other users)
N low-priority (Nice to other users)
L has pages locked into memory (for real-time and custom IO)
s is a session leader
l is multi-threaded (using CLONE_THREAD, like NPTL pthreads do)
+ is in the foreground process group 

psman page , 특히 PROCESS STATE CODES 부분.
